I've decided I need studded tires on my fat bike. The question is should I install studs myself on my existing 45NRTH Dillinger 5 26x4.6 tires or buy them already studded? I only briefly looked at the cost of DIY, the tool is just $8 but the studs when you consider 258 for each tire (I counted the stud holes) and now we're getting into some serious $. I often see used tires for cheaper than it will cost to DIY and also lesser brands new that are $100 per tire but I do not know the quality. The pre-studded 45NRTH stuff is expensive brand new. Can you suggest affordable options?
